No, there have been no attempts to domesticate the black-footed ferret. BFFs are extremely rare and endangered wild animals (there were once only 18 left in existence), and all breeding efforts are geared towards producing self-sustaining populations in the wild. It's possible that the small genetic variation in the black-footed ferret population (only 7 of those 18 animals successfully bred) would make it very difficult if not impossible to domesticate the species. I don't know why anyone would want to try. Linda [Posted in FML 7097]
